Carrier Roller Spring A11.00.105-01

Spring A11.00.105-01 is used in the undercarriage of HTZ crawler tractors and is designed for use in the sealed suspension assemblies. The spring provides the required axial force on the sealing components, helping maintain assembly tightness and protecting internal parts from dirt, dust, and moisture.

This spring is used in several undercarriage assemblies, including the track roller carriage, carrier roller, and front idler with the track tensioning and shock-absorbing mechanism. Thanks to its versatile design, the same part is used in multiple assemblies of the crawler suspension system.

Spring A11.00.105-01 works together with sealing rings, washers, and seal housings, maintaining constant pressure on the sealing elements and compensating for normal wear during operation. Its proper condition directly affects the service life of bearing assemblies and the overall reliability of the undercarriage.

During suspension maintenance or overhaul, it is recommended to inspect the spring, sealing rings, washers, and seal housings at the same time. Replacing worn components as a complete set helps maintain proper sealing and significantly extends the service life of the undercarriage.

Spring A11.00.105-01 is compatible with HTZ T-150, T-150-05-09, HTZ-181, and other HTZ crawler tractors with the same undercarriage design, as well as DT-75 tractors equipped with similar suspension assemblies.
